A copper alloy for bridle bits and similar items including 81 - 88%, by weight, of copper, less than 4%, by weight, of silicon, and the remainder zinc including impurities. The alloy is characterized by high strength and readily stimulates the horse to chew on the bit. The lack of nickel in the alloy is also safer for the horses.
Alliage de cuivre pour mors et articles similaires, incluant 81 à 88 %, en poids, de cuivre, moins de 4 %, en poids, de silicium, le reste étant constitué d'impuretés contenant du zinc. L'alliage est caractérisé par une résistance élevée et stimule facilement le cheval pour mâcher le mors. L'absence de nickel dans l'alliage est également plus sûre pour les chevaux.
